FRANK BENONA HOWARD, OF CEDAR HALL, QUEBEC, CANADA.

ARTICLE IIVIYANUFACTURED- FROM PULP.

SPECIFICATION forming part of Letters Patent No. 352,993, dated November23,1886.

Application filed January 22, 1886.

Be it known that I, FRANK BENONA How- ARD, of Oedar Hall, in the countyofBimouski, Province of Quebec, Canada, have invented new and usefulImprovements in Articles Manufactured from Pulp; and I do hereby declarethat the following is a full, clear, and exact description of the same.

This invention has reference to an improvement in articles formed ormanufactured out of wood pulp-such as sign-boards, panels, and otherarticles-upon which it is desired to have patterns, designs, figures, orletters, &c., raised upon or formed by depressions in'their surfaces.

That others may carry my invention into effect, I will now describe inwhat manner the same may be accomplished.

I take wood pulp as heretofore produced and form of it by any desiredprocess a cake, slab, mass, or block of suitable size to be acted uponby a pair of rolls having'upon either or both of them the pattern orpatterns to be imparted to the surface or surfaces of the pulp board tobe formed out of the aforesaid cake, slab, mass, or block, 810., ofpulp, it being remembered that where a projection is to be formed uponthe pulp board a corresponding depression must be formed upon the rollor rolls, and where a depression is to be formed upon the pulp board acorresponding projection must be formed upon the roll or rolls,and thatthe roll or rollswill be provided with any ing to whether the pulp boardthus produced is to have a pattern, &c., on one or both of its sides;for ilthe pulp board is to, be formed with a plain surface on one sideand an emthe rollswill be a plain cylinder, while the other Will be aroll having formed on it the reversed pattern, as above mentioned, tothat which is to be imparted to the one side of the thus produced may,according to the design or pattern formed on them, be used assignboards, panels forvarious articles of furniture, and other articles,coverings, or part cover-' ings for the walls and ceilings of buildings,and all such like and similar purposes. Furthermore, in certain cases itmay be desired to form the pattern or patterns upon the side Serial No.189,426. (S pecimens.)

figurated as above described, and by adding thereto embossments, to beattached by glue or other adhesive substances, or by nails, screws,860., to or upon the surface or surfaces or sides of the pulp boardproduced and coni of such said pulp boardsas, for example,

in the formation of sign-boards, the pattern of the sign-board anddesigns formed upon it may be imparted thereto by the rolls,whi1e theletters forming the name or other reading-- matter or numbers upon itmay be formed by letters or numbers attached, asaforesaid, to the saidpulp board; also, by the same process of forming embossed surfaces onpulp boards,

as above mentioned, by rolls, the detached embossments may themselves beformed by rolls having suitable recesses formed in them for thatpurpose.

In the drawings hereunto annexed similar letters of reference indicatelike parts. ure 1 is a front elevation of a pair of rolls used in themanufacture of improved articles from wood pulp. Fig. 2 is an endelevation of the rolls shown in Fig. 1. Fig. 3 shows a modification inthe situation of the rolls shown in Figs. 1 and 2 with regard to eachother,where:

by a different result is produced. Fig.4 shows the rolls A Ainoperation. Figs. 5 to 12, inclusively, show details of construction ofthe rolls. Fig. 13 represents inageneral manner the resulting orimproved article.

Letters A A represent a pair of rolls,either or both of which may beprovided with any desired projections or depressions for forming anydesired raised or impressed pattern, de-.

others may be formed.

In the drawings, the roll A is represented as being provided with apattern, while the roll A represents a plain cylinder. As shown,

the rollA is provided with a raised central, broad projection,-B, andtwo zigzag projections,O,situated equally distant at each side of theprojection B. If such pattern is to be ICO - &c.or by means of nails,screws, &c.

worked on indefinite lengths of pulp boards,it will extend continuouslyaround the roll, so that by passing a block,&c., of pulp D through therolls A A as shown in Fig. 4, the said pattern will be impressedcontinuously on one of its sides, as shown to the right of the hue w inFig. 13; but as shown in Fig. 2 the pattern does not extend completelyaround the roll A, but terminates as shown at E E. If the zigzag pattern0 is carried across longitudinally on the roll at the points E E, itwill give the pattern I, (shown to the left of the line min Fig. 13.)Again, I will suppose the projection B to terminate at or about thepoints F, and in a semicircular form. This will give a semicircular end,G, to the recess H, formed in the pulp board.

When the pattern to be formed on the pulp board is not a contihuous one,either or both of the rolls A A may be provided, if desired, withprojections K K,extending longitudinally the length of the rolls,topartly or completely sever the pulp board into required lengths aftereach impression, &c., of the pattern upon the pulp board; but thesecontrivances are only used in such cases as where they are required.

Figs. 5 to 12, inclusive, show a few of the more plain configuration ofsections of recesses and projections which may be formed in or upon therolls, either or both; but more elaborate ones may be formed, ifdesired.

In addition to the pattern formed upon the roll or rolls, and thusimparted to the pulp board, projecting additional designs, letters,

or figures may be attached to the pulp board either by adhesivesubstances-such as glIue,

example, on the space H (shown in Fig. 13) certain letters and numbers,either or both,

may be attached upon this surface to form any desired reading-matter;and in cases where it is desired to form a large number of such boardshaving the same reading-matter upon them, particularly in the case ofsign-boards for advertising such words as Sozodont,

Pain-Killer, St. Jacobs Oil, &c., such, may be formed upon the roll orrolls themselves in the manner above described for other patterns andimparted-to the pulp board along with or at the same time that any otherpatterns are imparted to the pulp board, as hereinbefore mentioned. I I

The pulp boards produced as above are afterward coated with awater-proof compound. Most of the water-proof compounds now in use forsimilar purposes are suitable for this, and the pulp board may bepainted, varnished, and gilded, all or any of these, as desired.

When it is desired to use the rolls as molds in which to form moldingsor embossments to be used as projections for attaching on surfaces forornamental or other purposes, the roll A, having formed recesses theconfigurations de sired into its surface, will be arranged with theplain roll A, as shown in Fig. 3, so that the peripheries of the tworolls bear upon each other,

and when so arranged masses of pulp are fed to the revolving rolls tofill the said recesses in the roll A. i

The portions of pulp filling the recesses in placed upon a fiat surfaceto dry, and when dry any superfluous fins or projections upon them maybe trimmed off by tools in an ordinary manner.

The pulp boards formed as hereinabove described can be used either inwhole or in combination with boards of natural-grown wood in theconstruction of articles of furniture or the like, and in such case theytake the place either in whole or in part of the use of wood board insuch constructions, and therefore supersede (in all cases where a stronghandsomely-carved yet cheap article, of any of the classes hereinabovementioned and many others, is desired) wood-carved boards.

I am aware that moldings, &c., have been formed by compressing paper inmolds and by rolling it between rolls, but all such I disclaim; also,that certain articles have been formed of pulp by pressing it intomolds. All such I disclaim, as they cannot in themselves or bythemselves be used in place of the pulp board described hereinabove, orin place of natural-wood boards.

What I claim, and wish to secure by Letters Patent, is as follows:

1. As an improved article of manufacture, a pulp board having patternsor configurations rolled into its surface, the whole substantially asdescribed.

2. As an improved article of manufacture, a pulp board having patternsor configurations rolled into its surface, and having additional proecting configurations or embossments attached upon its surface andafterward coated with a water-proof compound, the whole substantially asdescribed.

3. As an improved article of manufacture, a pulp board having projectingpatterns or configurations rolled thereon and impressed patterns rolledthereinto, with additional proj ecting patterns or embossments attachedthereon, the whole afterward coated with a water-proof compound, thewhole substantially as described.

4. As an improved article of manufacture, a pulp board having projectingpatterns or configurations rolled thereon and additional projectingconfigurations or embossments attached thereto and afterward coated withwater-proof compound, the whole substantially as described.

5. As an improved article of manufacture, a pulp board having projectingpatterns or configurations rolled thereon, the whole substantiall y asdescribed.
